The emergency treatment method of sewage mixer fault is mainly formulated according to the specific fault type and severity. The following are some common faults and their emergency handling methods:

First, the submersible mixer vibrates or shakes

Emergency treatment method:

Increase the submersion depth: If the vibration is caused by insufficient submersion depth, stop the machine immediately and increase the submersion depth of the mixer until the vibration stops.

Check and adjust the equipment: If the pool capacity is small and the mixing is too violent, you can consider temporarily reducing the speed or power of the mixer, and then restore it after the sewage condition in the pool is improved. At the same time, check whether the guide rod support installation foundation is loose. If it is loose, strengthen it immediately.

Check the impeller: If the impeller is damaged, the spare impeller should be replaced in time to ensure that the mixer can continue to work.

Second, the load current is too large

Emergency treatment method:

Check the rotation direction: confirm that the rotation direction of the mixer is correct, if wrong, stop immediately and adjust the rotation direction.

Clean the impeller: check whether the impeller is blocked by debris. If there is a blockage, stop the machine immediately.

Adjust the gap: If the guide hood and the impeller interfere, the gap between the two should be adjusted to the appropriate position.

Stop inspection: If the above measures are ineffective, and the load current continues to be too large, stop to check whether the motor and transmission parts are damaged, and replace the relevant parts if necessary.

Third, abnormal noise

Emergency treatment method:

Stop check: Stop immediately when you hear abnormal sound, check whether the guide hood and impeller interfere, if there is interference, the gap should be adjusted.

Replace the bearing: If the bearing damage causes abnormal noise, the spare bearing should be replaced in time.

Fourth, stator overtemperature alarm

Emergency treatment method:

Stop cooling: After receiving the stator overtemperature alarm, stop immediately and let the mixer cool naturally.

Check the alarm device: check whether the stator overtemperature alarm device is damaged or false alarm, if damaged, the alarm device should be replaced.

Check the motor: If the motor is really overheating, check whether the motor performance is reduced or damaged, and replace the motor if necessary.

Fifth, oil chamber leakage alarm

Emergency treatment method:

Stop inspection: After receiving the oil chamber leak alarm, stop the machine immediately to check whether the mechanical seal is damaged or loose.

Replace the seal: If the mechanical seal is damaged, replace the spare seal in time.

Oil change and observe: Restart the mixer after replacing the new lubricating oil, and observe whether there is still leakage phenomenon. If the leak persists, it should be further examined and dealt with.

General emergency handling recommendations

Keep calm: When encountering any fault, the operator should keep calm and handle the fault according to the operation rules and emergency plans.

Timely report: For failures or major failures that cannot be solved immediately, report to the superior in time and request support.

Ensure safety: During troubleshooting, ensure the safety of the human body and the device to avoid secondary accidents.

Please note that the above emergency handling methods are for reference only. The specific handling measures should be adjusted according to the actual situation and the equipment manual. At the same time, in order to ensure the long-term stable operation of the sewage mixer, it is recommended to carry out regular maintenance and inspection.
